umm well yesterday i played and did 30min. So thats better. My teacher doesn't play to me -of course he does know how to play the trumpet. he tells me to play and says if ti right or wrong. He does talk about his old times and also talk about the trumpet history, valves, mouthpiece etc. I dont know if his a good teacher or not. i mean he has lots of people going to him for different things. Piano, clarinet, saxophone. There some of the things he also teachers. He has his own doctors and police cops that go to him for learning. If i leave him i will have to travel 45min Each Saturday after work for a half an hour session. With this guy a get 45-60min a session. His strict as well so wen i do something wrong he tell me how to do it.
